Flower Size .6" [1.5 cm]

Found in Peru on the Amazon slope at elevations around 2250 meters as a medium sized, cold growing lithophyte with a simple, cane-like, laterally compressed, somewhat thickened towards the middle, straight stems carrying 9, along the apical half, alternate, subcoriaceous, lanceolate, bilobed, with a low dorsal keel, glabrous, margin entire, articulate below into the base leaves that blooms in the later summer on a terminal, suberect, paniculate, laterally flattened, glabrous, to 90 flowered inflorescence with 3 slightly arching branches, the peduncle and branches provided with widely triangular, acute bracts and much shorter than the ovary, triangular, acute floral bracts and carrying simultaneously opening, resupinate flowers without color and fragrance data.

"Epidendrum ancirotylosum Hágsater & E.Santiago 2004 GROUP Amblostoma SUBGROUP Amblostomioides characterized by the caespitose habit, the thinly fusiform stems carrying narrow, apically bilobed, subcoriaceous leaves distributed towards the apical half of the stem that blooms on an often large, apical, erect, paniculate infloresence carrying greenish yellow to white flowers with a 3 lobed lip and with the ovaries and sepals usually dorsally pubescent. The species has short, thickened stems, an erect, relatively large, paniculate inflorescence, the rachis glabrous, heavy flowers, the ovaries pubescent, the sepals dorsally sparsely short-pubescent, petals linear, falcate, and the lip deeply 3-lobed, the lateral lobes obliquely oblong-reniform, the midlobe narrowly subrhombic, obtuse, bicallose, the calli with a cuniculus beneath them, and a semicircular, anchor-shaped structure in front. It is somewhat similar to Epidendrum pubiflorum C. Schweinf. which has the rachis finely pubescent, slightly larger flowers about as heavy looking, but the petals are .08" [2 mm] wide and the fip is bicallose and 3-keeled, the lateral lobes dolabriform and the midlobe cuneate, truncate. Epidendrum lanipes Lindl. has larger plants and flowers strongly fragrant of citrus, the rachis as well as the ovaries are pubescent, lateral lobes of the lip semiovate, midlobe cuneate, retuse, bicallose with three short keels in front."
